About Redact PDF

Redact PDF permanently blacks out sensitive text and areas, such as names, account numbers and addresses. Drag over what you want to hide, or search for a word to mark every match. Redacted pages are turned into images and the document's metadata can be removed, so the hidden content can't be recovered.

Frequently asked questions

Is Redact PDF free?

Yes. Redact PDF is free to use, with no sign-up, no watermark and no daily limit.

Are my files uploaded to a server?

No. Paperwing processes your files inside your browser, on your own device. They are never uploaded, and they are cleared from memory when you close the tab.

Does it work on my phone?

Yes. Paperwing works in any modern browser on Windows, Mac, Linux, Android and iPhone, with nothing to install.

Is there a file size limit?

Each file can be up to 300 MB. Very large files depend on your device's memory, so a computer handles them faster than a phone.
